ASSESSMENT OF HYDRAULIC EFFICIENCY OF IRRIGATION BY MEANS OF A SPRINKLER

Abstract

The article describes the methods of some field studies to assess the efficiency of sprinkler irrigation systems and their reliable design. The distribution of water consumption over the irrigation system area and its losses are also analyzed. The Christiansen distribution coefficient C_u is used to estimate sprinkler water distribution. It was calculated by examining three types of combinations using the Catch Can method, that is, sprinkler height, sprinkler water flow, and pressure variation. To determine the Christiansen factor, it is calculated from the sum of the experiments, taking into account the distribution of flow over the height of the fill at several different pressures. The research was conducted on the farm “XXI asr xirmoni” of the Uzbek district of Fergana region. Based on the given method, the optimum height was determined when estimating the water distribution. Based on the field experiments and their analysis, a graph based on the irrigator height and flow distribution was plotted.
